Alexander Puck Neuwirth
Theoretical and computational particle physicist working on precision predictions for high-energy collisions: perturbative QCD and electroweak corrections, photon production, and Monte Carlo event generators.
I am a research fellow in the Dipartimento di Fisica "Giuseppe Occhialini" at the University of Milano-Bicocca. I completed my PhD at the University of Münster, where I worked on combining fixed-order QCD calculations with parton showers for real and virtual photon production. Alongside this research, I develop open-source scientific software (pylhe, LHEUTILS) and contribute to shared particle-physics infrastructure, including LHAPDF, HepMC, Rivet/YODA and Gentoo Linux.
